The `to_string()` for this is modified a little from the original,
because we have to calculate what the layer-count is then, instead of
having it already calculated.
We don't need to check if a function parameter is already declared
while creating bindings for them because we deduplicate their names by
storing them in a hash table in one of the previous steps.
This change makes React-Redux-TodoMVC test in Speedometer run 2%
faster.
The existing implementation has some pre-existing issues where it is
incorrectly assumes that byte offsets are given through the IDL instead
of UTF-16 code units. While making these changes, leave some FIXMEs for
that.
This is required in porting over CharacterData from DeprecatedString to
String.
Unfortunately, as with ParentNode, we cannot yet remove the
DeprecatedString variants of these functions as the Element interface
includes ChildNode and has not yet been ported over from
DeprecatedString.
This allows applying SVG <mask>s to elements. It is only implemented for
the simplest (and default) case:
- mask-type = luminance
- maskContentUnits = maskContentUnits
- maskUnits = objectBoundingBox
- Default masking area
It should be possible to extend to cover more cases. Though the layout
for maskContentUnits = objectBoundingBox will be tricky to figure out.
This allows SVG mask elements to have layout computed, but not connected
to the main paint tree. They should only be reachable if (and painted)
if referenced by the "mask" attribute of another element.
This is controlled by the forms_unconnected_subtree() function on the
paintable, which (if it returns true) prevents the paintable from being
added as a child to what would be its parent.
A Paintable is not created for an SVG <defs> element (nor should it),
but it can contain SVG <mask> elements that need a paintable.
This change forces those paintables to be created (without a parent).
The masks are then only painted by being referenced from another
element.
This change moves steps that can be executed only once and then reused
in subsequent function instantiations from
`function_declaration_instantiation` to the ECMAScriptFunctionObject:
- Determine if there are any parameters with duplicate names.
- Determine if there are any parameters with expressions.
- Determine if an arguments object needs to be created.
- Create a list of distinct function names for which bindings need to
be created.
- Create a list of distinct variable names for which bindings need to
be created.
This change makes React-Redux-TodoMVC test in Speedometer
run 10% faster :)
Unless a new toolchain update has been merged, users should not need to
rebuild their toolchain. Yet, the first thing they see in the build
documentation is to run `Meta/serenity.sh rebuild-toolchain`, which
might incorrectly lead them to use it whenever they encounter an error.
This is a waste of time and causes frustration.
Move any mentions of this option to `Troubleshooting.md` and add a note
to `BuildInstructions.md` about the toolchain build being a one-time
endeavor.
This is in the spirit of commit a4692a6c97
(and the history behind that commit).
We will need to perform lookups from an integral node ID to the JSON for
that node frequently in the Inspector. We will also need to traverse the
DOM tree from a node, through its ancestors, to the root node. These are
essentially the same maps stored by the Qt Inspector widget.
This commit includes only fetching the DOM tree from the WebContent
process and displaying it in an NSOutlineView. The displayed tree
includes some basic styling (e.g. colors).
